Bipolar diathermy or ligation for haemostasis in tonsillectomy? A prospective study on post-operative pain.

Forty-nine children for tonsillectomy were entered in a prospective controlled single blind study to compare the post-tonsillectomy morbidity of bipolar diathermy as opposed to ligation for haemostasis. We found no significant difference in post-operative discomfort nor reactionary or secondary haemorrhage in the two methods used. This is the first controlled trial where bipolar, rather than unipolar diathermy is used, and compared with ligation in the operation of tonsillectomy.
